I am trying to turn on the LD3 LED (connected to PB3) on the NUCLEO-L031K6 board using direct register access without libraries, but it is not working. The LED does not turn on. I have configured the pin control register, enabled the GPIOB clock, and...
Quick Question.... The Docs say the STM32F767VGT6 has 166 5 V tolerant I/O's I need to put 5V pullups on some of my OUTPUT I/O !Is the tolerance just for INPUTING ?orWill the Low transistion with a 5V pullup say 1K be ok !
Hi, i hope you're having a great daySo i'm working on a project involving a stm32f4 and multiple other components (an ADC and a amplifier).The stm32 is connected to the ADC via I2S and to the amplifier via I2S and also I2C.I first soldered the stm32...
I'm working on a solution using STM32H753 MCU. HRTIM1 TIMA needs to generate short periodic 100 ns pulses periodically and drive MDMA channels. This already works fine.In addition to above, I need to drive GPIO F8 low for a short 500 ns time window t...
I'm trying to do something that seems simple if you go a search. I want the module to sleep. Then I will wake it with voltage on pin B6. I don't want an interrupt. Just an event. People mix event and interrupt so much and all the examples I see are b...
Is it possible to change the FLASH write protection at run time without reprogramming the option bytes?The write protection registers are writeable after unlocking, but it appears as if changing the value has no effect on the actual write protection;...
I am using stm32f103c8t6 with uart cable to connect it with stm32 cube programmer but come up the statement above. Any suggestion to fix this problem?14:12:16 : Serial Port COM3 is successfully opened. 14:12:16 : Port configuration: parity = even, ba...
Hello everyone,I'm current creating my first STM32 design using STM32F411 and have a need for the USB function on the MCU. The datasheet states that it requires a 48 MHz clock generated by a PLL connected to the HSE oscillator.And I've currently chos...
Hello,I dug deeper into PSSI behavior, and and I observed unwanted behavior. From my point of view it is a bug.PSSI is configured as:OUTEN = 1 (transmit mode)CKPOL = 0 (outputs driven on rising edge, inputs sampled on falling edge)RDYPOL = 0 (0 at in...
Dear,Recently, when working with STM32U575 and using WWDG, I've encountered an unclear behavior when I set the controller to STOP mode by using HSE or HSI clock source.By using HSI and LSE clock source (See below code), when enter STOP mode, WWDG is ...
