WebIf I reset continously the uC (maybe interrupting the SPI communication would do the same) sometimes the receive buffer gets a 4-bit offset. I do communicate with 8-bit values. These offset breakdown may hole communication, because I will look for a start delimiter but so a never receive one. I will implement now a detection if I'm in this state. WebFeb 7, 2024 · 9. Hello. I am trying to interface GP22 with stm32f103ze microcontroller. I am unable to figure out if proper communication has been established between GP22 and uC. All the necessary components have been added to the GP22 IC following the datasheet. Also all the connections have been made between the GP22 and the Micro controller.
