1) I've checked multiple schematics for blue pill, black pill, etc., and saw capacitor and resistor on reset button line. I've built a test (pinout) board and without any capacitor or resistor. I can reset it (NRST pin to ground). May this cause a ha...
I'm trying to get an RTC timestamp from an external event down to the us. My plan is to output the 1Hz calibration from the RTC and externally tie that to TIM8-CH1 as an input capture (reset-on-capture). The external event would route to the RTC time...
Hello, I use USART1 routed to PA9/PA10 (AF1 as per data sheet), so executing the line SYSCFG->CFGR1 |= (SYSCFG_REMAP_PA11 | SYSCFG_REMAP_PA12);should present the GPIOs PA9 and PA10 to pins 16 and 17 of the TSSOP20 package. Right?Well, pins 16 and 17 ...
Hi,I have a design where ADC channel 11 is used for sampling BLDC motor current via shunt resistor.If motor is stopped it can be observed a spikes with aplitude 200 mV directly on the MCU pin PB10 to which the ADC channel 11 is connected.The spikes h...
It finally happened, i need two pins without pwm functionality to output pwm signals (minimum 1kHz)Im using an STM32f072R8Tx clocked with HSI48Mhz, my TIM1 is available.My idea is:TIM1 channels 1 and 2 set up as PWM NO OUTPUT with interruption enable...
Hello , I want to use i2c half call back, but i didn't found this function. İ am wondering is there any function.
Hi,I am trying to connect to a 16 bit parallel display interface. To write new data, I have to use pins on five different ports (GPIOs A, B, C, D, E). Right now I am setting these pins like this:PORT_D15->BSRR = (PIN_D15 << 16) | (((data >> 15) & 0x...
Hello,I've been using the STM32L5 FDCAN HAL Driver but I have some problems with it.When i try sending some CAN 2.0 frames to the STM32, an isr is called and the error Message RAM access failure is raised.Sometimes, the ACK is sent but the interrupt ...
Hello,I am working on SAI part of the NUCLEO-F756ZG board and I observe an issue with the DMA.The configuration is:SAI A as a master with master **** out and audio mode = master receive. SAI B as asynchronous slave and audio mode = slave transmit. (S...
