Dear all,
I am new to stm32 and i am trying to make my stm32f103 nucleo communicate with an other stm32f within the cubef1 is a nice working example:I2C_TwoBoards_ComIT
i have only 1 problem with this part of the code:
/* While the I2C in reception process, user can transmit data through ''aTxBuffer'' buffer */
uint8_t aTxBuffer[] =
''I send this''
;
while
(HAL_I2C_Master_Transmit_DMA(&I2cHandle, (uint16_t)I2C_ADDRESS, (uint8_t*)aTxBuffer, TXBUFFERSIZE)!= HAL_OK)
{
/* Error_Handler() function is called when Timeout error occurs.
When Acknowledge failure occurs (Slave don't acknowledge its address)
Master restarts communication */
if
(HAL_I2C_GetError(&I2cHandle) != HAL_I2C_ERROR_AF)
{
Error_Handler();
}
}
however the only data you send over the i2c lines are text converted to binary, which means you cant send all sorts of bytes.
is there a way to make the format of data I send to hexadecimal or decimal?
#example #i2c #stm32f103
