I’m trying to write a buffer of about 60 bytes out of uart3.
It only writes between 15 and 22 bytes.
For my testing the data in the buffer doesn’t change.
It’s not shown here but I’ve used print to confirm the buffer is filled with the correct data.
Any idea of what might cause this?
uart = pyb.UART(3, 115200)
uart.init(115200, bits=8, parity=None, stop=1) # init with given parameters
def AssembleMessage(msgBody):
dataLen = bytes([len(msgBody)-1])
chkSum = bytes([CalcCheckSum(msgBody,len(msgBody))])
msg = MAGIC_BYTES
msg += dataLen
msg += msgBody
msg += chkSum
bytesWritten = uart.write(msg)
print(bytesWritten)
#uart.write(MAGIC_BYTES)
#uart.write(dataLen)
#uart.write(msgBody)
#uart.write(chkSum)
Regards,
Greg
