Hello,I have been looking into this RTO flag provided in STM32F303 UART.According to the manual"The timeout function and interrupt must be activated, through the RTOEN bit in the USART_CR2 register and the RTOIE in the USART_CR1 register. The value c...

I am trying to communicate with an adc chip acting as a spi slave to my stm32f3 spi master. So far I am unable to make it work.After attaching an oscillscope I found out that if i send only 8 bits of data to the slave , I get exactly 16 clock pulses ...

you're right I just found it a few seconds ago and have been banging my head. Thanks

omg I am such an idiot. The duration to transmit one bit at 115200 is 8.6 microseconds not 86 micro like i mentioned in my original post.With the correct value I have to put 345600 in RTO register to timeout after 3 secs and then it works fine.For in...

USART1 on STM32F303RE.The RTO does time out after a few seconds if I enter a random big value like USARTx->RTOR = 1000000; (in this RTO interrupt will fire after 8 secs of last sent character) so it seems to be working but I cannot understand the ca...

I moved the HAL_GPIO_WritePin line just before my write_cmd and now it seems the slave chip is responding fine.HAL_GPIO_WritePin(SPI_CS_GPIO_Port, SPI_CS_Pin, GPIO_PIN_RESET); write_cmd(LOCK_KEY_READ); recv_reg = write_cmd(0x00);Previously I ...

I have configured a GPIO pin as slave select and I do a manual SET/RESET on this pin. The ADC is Analog Devices 7913
