Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : Armmite L4: V5.05.02 - 64 pin support

Please find attached version 5.05.02. This now includes support for 64 pin variants, the STM32L433RCT6 and the STM32L431RCT6 as well as 48 pin and 32 pin. The software automatically configures for the number of pins. I've done the development on a STM32L431RCT6 on a breakout (pic below) but the code should run well on a NUCLEO-L433RC. With all the STM32L4 the mandatory connections are:

all VSS and VCC including VSSA and VDDA, each pair decoupled close to the chip with 0.1uF ceramic caps
BOOT0 10K to GND
NRST 10K to VCC and direct to ST-LINK
Console TX and RX to USB/UART (or ST-LINK)
SWDIO and SWCLK to ST-LINK for programming
32KHz crystal to OSC32-IN and OSC32-OUT with 6pF caps to GND - NB this is essential for the firmware to run
VBAT (N/A for 32-pin) to VCC or to 3V battery

2018-12-06_060203_ArmmiteL4.zip




Pinout for the 64-pin chips is

Hi matherp
Great work
Now we have all family 32/48/64pin STM32L4.
In your roadmap, is the management of the usb? or these new micro with mmbasic will be so without the usb?
Thanks
Antonio

There is a typo in the pinout chart - the "COM2-Rx" comment is shown twice, once for pin 30 and again for pin 43. It looks like pin 43 should be COM1-Rx, but that is only my guess.

The same problem exists in the pinout chart for the 48 pin ARMmite L4 but the pin numbers are different of course.

Phil.

  Quote  There is a typo in the pinout chart - the "COM2-Rx" comment is shown twice


The joys of cut and paste, yes it should be COM1-RX

Here is updated firmware. Note that for the 64-pin the console-RX pin has changed to pin 17 to match the NUCLEO-L433RC. I've also changed the console-RX pin on the 48-pin to make wiring easier. Finally, I've corrected omissions in the analogue pins.

Minor update that fixes a bug in COM2 for 48-pin and 64-pin parts - COM2 does not exist on 32 pin chips

Hi matherp
To have more analog possibility, it is thinkable to move SPI from PA1/6/7 to HW SPI2(PB10/14/15)?, but in PB10 i see com2-tx. On 48pin
If we use actual SPI2 for external memory and SPI for other device, DAC etc remain a fee of analog pins free.
What do you think about it?
Thanks
Antonio

Can't do anything about SPI and stay compatible with the 32-pin chip but what I can do is implement SPI3 for the 48-pin and 64-pin parts

Version 5.05.03

2018-12-07_011215_ArmmiteL4.zip

Same syntax as commands and functions SPI and SPI2

Pins are:

Signal 48-pin 64-pin
SPI3-CLK 26 34
SPI3-IN 27 35
SPI3-OUT 28 36


These pins are not analogue capable so by using SPI3 instead of SPI for your devices you free up 3 analogue pins

Hi matherp

Thank you, this is the best solution you could get.
Some questions:
- OPTION FLASH CSpin use only work only in SPI2, but we can use SPI2 for other device playing with different CS?
- OPTION LCDPANEL with SPI(1)?
- What about the PWM? do you already have an idea of which pins?

Thanks
Antonio

Minor update that now allows the RTC to be read at millisecond resolution

2018-12-07_211451_ArmmiteL4.zip



I'll also include this functionality on the Armmite H7 next release.

  Quote  OPTION FLASH CSpin use only work only in SPI2, but we can use SPI2 for other device playing with different CS

If you use flash then SPI2 can also be used for an LCDpanel

  Quote  OPTION LCDPANEL with SPI(1)?

No: see answer to last question

  Quote  What about the PWM? do you already have an idea of which pins?


See below; note PWM1C and PWM1D share the same pins as COM1 TX and RX so you can't use both at the same time. you can use PWM1A and PWM1B at the same time as COM1.

32-PIN
{ NULL, 0, PUNUSED , NULL, 0,}, // pin 1 VDD
{ NULL, 0, PUNUSED , NULL, 0}, // pin 2 OSC32_IN
{ NULL, 0, PUNUSED , NULL, 0}, // pin 3 OSC32_OUT

This whole effort is really great! Matherp, have you tested the power use on the 48 and 64 pin, or should it be about the same as the 32 pinner? Nice time function there also!!!


Edit...

A quick question on com1... When using com1 for RS485, can the de pin be switched to either active high or active low preventing the use of an external inverter when using a transceiver chip?Edited by viscomjim 2018-12-09

I found an 'anomaly' with the millisecond time.

  Quote   OPTION milliseconds OFF
timeout
DO
t$=TIME$

LOOP UNTIL RIGHT$(t$,1) = "0"
OPTION milliseconds ON

SETTICK 10000, timeout

timeout
DO
LOOP

SUB timeout
PRINT " ";TIME$;" ";DATE$
END SUB


produces this output:

The problem is when the time has zero milliseconds.
19.1000 rather than 20.000

Is it working at a higher resolution behind the scenes and 1000mS is really 999.9?

Jim

I did another run and this time one of the outputs was correct

  Quote  I found an 'anomaly' with the millisecond time.


Very interesting. The issue is that the time in seconds, minutes, hours is latched in the RTC so you always get consistency. The milliseconds are based on a free running register that counts down from 4095 to zero each second. So it seems the register can be at zero but the main "time" has not yet latched in the change of seconds. I'll have to put in some sort of software "frig" to correct this - not sure what though. I certainly don't want to have to write a complete calendar function to deal with seconds/minutes/hours/... rollover

A crude 'round down'
IF milliseconds >= 1000 THEN milliseconds = 999

No, too nasty

Try this:

2018-12-08_195738_ArmmiteL4.zip

Here is my test program

CPU 8
Option milliseconds off
a$=Time$
Do
Loop Until a$<> Time$
Option milliseconds on
Pause 990
Do
Pause 999
Print Time$
Loop

More problems
I was going to ask if we can have negative EPOCHs because I was born before 1/1/1970.
I have found that it doesn't like dates last century.
> print epoch("08-04-1972 00:00:00")
Error: Invalid date

I just used Geoff's standard parsing for the "DATE$" command

if(d < 1 || d > 31 || m < 1 || m > 12 || y < 2000 || y > 2999) error("Invalid date");


but that is easily fixed.

2018-12-09_205542_ArmmiteL4.zip

The linux time routines that I use don't work before 1970 (it wasn't invented by then) - sorry

NB I've also changed the format of the DAY$ function as per a change I've just made on the Pi-cromite

Just for you, I've found some different time routines so EPOCH and DATETIME$ now work back to 1902 with epoch going negative before 1970.

Thanks Peter.
The arguments about negative epoch are nearly as devisive as Brexit.
It is about time C and it's derivatives went 64 bit by default.
