STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I used STM32F103C8 series of chips, now I design four keys, the corresponding IOs is PC13,PC14,PC15 and PB11. The problem is that PC15 and PB11 cannot be used as input at the same time.As long as these two pins are not input at the same time, the res...
Now , I generate below waveform. Every thing is OK except for red arrow , it indicate a deadtime.but it's longer than other deadtime , in fact , This dead time is twice as large as the other dead time .divide into three stage :1�?First Stage , TIM r...
Hello , now I debug about Complementary output with dead-time feature of TIM1 CH1 and CH1N, I set deadtime 5us ,and TIM1's period 50us , then I get scope via oscilloscope ,but the scope is not what I expect , refer to below , In fact DT1 == 2...
Hi Everyone,We are using the following code to generate clock pulse for STM32F722 from an external 12MHz crystal. However, whatever we do it sounds the STM32F722 gets its clock pulse from an internal 16 MHz oscillator. The reason for using an extern...
I am using a Nucleo F429ZI. I have noticed when I plug it in via the debugger, my computer treats it like an external drive (which it calls NODE), where it seems I can store stuff. Is it possible to store a text file in this space generated from my p...
Hi there, I'm using the SAI2_FS_A signal to trigger a capture event on TIM2 (Through a series of weird internal routing). It all works nicely when SAI2 is an asynchronous master, however in my application it needs to be a synchronous slave to SAI1. I...
Hi there, I'm using the STM32H7 and I need to get one of the SAI FS signals to go through a pre-scaler and trigger a capture compare on TIM2 CC3.The only solution for this seems to be to use SAI2_FS_A -> TIM5_ETR1 -> TIM5_TRGO -> TIM8_ITR3 -> TIM8_TR...
I think I read that I can do this "ON THE FLY" - without DEINIT - REINIT the ADC but I'm getting odd results. Seems sometimes it switches and sometimes it does NOT ?I'm going to tinker a bit further but if I am missing a "forest for the trees" thing...
We need to Smbus Communication to use BQ78350(Texas Instrument) with STM32F051R8T6. We studied the example codes in your website. (https://www.st.com/en/embedded-software/x-cube-smbus.html) But the examples are so complicated to understand. We need t...
I'm trying to send message to sim900A via the serial port. The AT commands work but the GSM replies with some unwanted text (Previously sent text ) then finally OK. The GSM is supposed to reply what I typed with some prompts and finally OK. The pict...
