One more release today (good progress  ) 5.04.14 but don't miss details of 5.04.13 on page 2 of the thread.
2018-06-21_044222_Armmite.zip
This includes serial port support. There are 4 H/W serial ports (in addition to the console) with full H/W interrupt support. All functionality is implemented as per the MM+ with the exception of RS485 support (to come later). By default the RX pins are pulled high but this can be disabled with:
| OPTION SERIAL PULLUP DISABLE |
|
|
and re-enabled with:
| OPTION SERIAL PULLUP ENABLE |
|
|
pins are:
COM1_TX_PIN 101 //PA9
COM1_RX_PIN 76 //PB15
COM2_TX_PIN 36 //PA2
COM2_RX_PIN 37 //PA3
COM3_TX_PIN 136 //PB6
COM3_RX_PIN 73 //PB12
COM4_TX_PIN 110 //PA15
COM4_RX_PIN 18 //PF6 |
|
|
This just leaves PWM and analogue input to code and the STM32 will be close to the MMX in functionality.

Very very GOOD JOB!!
I don't understand STM Nucleo logic
For com1, they have not connected pins with D0/D1 Arduino who is used as "hardware serial" in many shields

That is my allocation - I'll change it so COM4 is on those pins. I'll also change I2C so it is on the normal Arduino pins - watch this space

No, you have good idea to use this pins, I have think that STM connect d0/d1 on UART1 rx/tx but no, they are connected on signals PG6/PG14 as USART6 (and also SPI1  )

Please find attached V5.04.15
2018-06-22_173716_Armmite.zip
This has some pin changes as follows (puts com4 and I2C onto the Arduino header):
COM1_TX_PIN 101 //PA9 USART1
COM1_RX_PIN 76 //PB15
COM2_TX_PIN 36 //PA2 USART2
COM2_RX_PIN 37 //PA3
COM2_EN_PIN 118 //PD4
COM3_TX_PIN 136 //PB6 UART5
COM3_RX_PIN 73 //PB12
COM4_TX_PIN 129 //PG14 USART6
COM4_RX_PIN 124 //PG9
I2C_SCL 139 //PB8
I2C_SDA 140 //PB9

Note that COM2 now supports an enable pin (active high) for driving RS485 transceivers. This is enable by adding "DE" to the open command - see example below:
There are also changes to the other parameters for opening serial ports.
"9BIT" is no longer valid - do not use
"ODD" adds an odd parity bit (making 9 bits if normal 8-bit data is sent)
"EVEN" adds an even parity bit (making 9 bits if normal 8-bit data is sent)
"7BIT" reduces the data to seven bits (total of eight if parity is specified)
other parameters (INV, S2, OC) are as the MM manual
In addition you can now specify a transmit completion interrupt as well as a receive interrupt. This works on any of the 4 com ports - see the example.
This example outputs a "proper" modbus RTU message (8 data bits + even parity)
Open "com2:9600, 1024, myrxint, 256, mytxint, de, even" As #1
For i=2220 To 2400
Print #1,Str$(i,4)+" ";
Next i
Print #1,""
Do
Loop Until k=1
close #1
end
Sub myrxint
End Sub
Sub mytxint
Print "TXcomplete"
k=1
End Sub |

yesss!!
1000 thanks peter 
here pinouts excel sheet with signals names
2018-06-22_191039_NUCLEO-H743ZI-pinout2.zip
I can translate my modbus/gps app on this card

This has LONGSTRING, JSON, and background GPS functionality as per the MMX (see MMX manual for details).
In addition RTC SETTIME is removed. Setting the STM32 RTC is done by setting TIME$ and DATE$. the day of the week is automatically calculated for the date and will always be available once DATE$ is set by using the DAY$ function. If the battery backup to the STM32 RTC is connected (remove SB156 first) then the time and date will be correct immediately on power up.

I have successfully run the SSD1306 Basic Driver.
There were only a few minor changes to Peters original code.
I used FONT 1 instead of a loaded font and changed the syntax of the ON ERROR SKIP lines.
Together with the RTC, I now have another clock.
I might try a bigger display next.

I have added a sheet for the Arduino connector pinouts.
2018-06-23_160355_NUCLEO-H743ZI-pinout3.zip
I have also changed all pages to refer to the CPU sheet for the pin notes.
This way you only have to update the one sheet and the changes should reflect on the other sheets.
I left the original sheets intact in case I have made too many mistakes.

This implements loadable fonts (and possibly Cfunctions if I knew how to compile them for the H7  ). It also fixes the reporting of OPTION LCDPANEL USER

This is deliberate and I think the same on the whole MM range. This is because bad things could happen if the Basic routines were not loaded when the MM restarts.
The SSD1306 driver program example now works without any changes
