I have a STM32L4xx series microcontroller. My goal is to use RTO in USART to issue a timeout, from the time a read was attempted (not only from the last stop bit). This is needed as its possible for nothing to be received. How do I acheive this using RTO?

I've setup USART to interrupt on a timeout using:CR2.RTOENCR1.RTOIEAnd configured the timeout using:RTOR.RTOIt works great, really nice feature. The RTO timeouts are always measured from the last stopbit/character received. However, I need to support...

Accessing outside flash area is working...

Tested to flash a 128k (STM32F105) device with a firmware (40k) that is compiled for 256k and it works. Even when the firmware reads and writes data (config) to address location 0x0083E000 which is way out of the 128k device memory area.Is there some...

Resolved! STM32G070RB HSI16 Clock and clock calibration issues. Is there a clock calibration example without the need to use HSE or LSE clocks?

I am trying to acquire the amount of ticks a timer counts using a 50Hz signal (acquired from the mains using hardware). For this I use a EXTI8 interrupt where the 50Hz signal is sampled. I can see on the scope that this interrupts works perfectly (by...

Software SS management issue of H753's SPI

On Fig 613 of RM0433, the SS connects to Vcc. According to 50.4.7, it is said the SS pin is free for GPIO when in software SS management mode.Does fig 613 mean SPIx_NSS pin can not be used GPIO when corrsponding SPI in software SS management mode?
