Hi,I recently bought a ST-LINK/V2 dongle and it didn't work. I checked the insides of it to see that the microcontroller inside wasn't an ST one, but a Geehy clone microcontroller. I bought another, which was not a dongle, it was the larger white ver...
Hi all,I am using the NUCLEO-F446RE with the STM32F446RE. I am trying to interface with an external dual sampling differential ADC: ADS9224R.ADC Timing DiagramThe ADC can provide samples at up to 3M/s. I would be happy to achieve ~0.8M/s sampling.I h...
Hi,I am trying to receive data (on STM32L083) via USART1, the way I was used to doing it on STM32L071. Specifically, I used a circular buffer that was continuously written to by DMA - RX. Now, I've ported the code to this L083 and it seems that nothi...
Hi all,I am using a STM32L476RG NUCLEO Board with FreeRTOS and STM32 iCUBE LoRaWAN stack. I have a UART interface connected to Raspberry Pi, which periodically sends and receives data to-from STM32. I am using a circular buffer with DMA and IDLE Line...
My question is related to the stm32u575 and bu585's board definitions in the Zephyr Project. Actually, there is no question related to the hw design.I shared these questions on the Zephyr repo but no one has given an answer yet.https://github.com/zep...
Hello,We have this part MPN#STM32L431RCT6TR with labels not matching the top markings.Labels is with 7and top markings with Z .See photo below.Please let us know if this are ok.Thank you in advance!Best Regards,Winnie
Hi,I am quite new to STM32 MCU family and have a quick question. I attached schematic for the reference. Is STM32F103CBT6 capable of driving complementary 50 kHz of PWM signals(HI and LO) with configurable duty cycle for the gate driver IC? Yes, I am...
Hi, which is the maximum analog output voltage from the STM32H723ZG? In the datasheet I saw that there are two Op-Amp inside the MCU with gain from 2 to 16. How can I use this Op-Amp? I have to do something about the hardware or I have just to write ...
Is USART1 on APB1 (AN5593, tab.17) or APB2 (DS, RM, CubeMX) and USART2 on APB1 (DS, RM, CubeMX) or APB2 (AN5593, tab.17)? Guess, there is an issue in an5593-how-to-use-the-gpdma-for-stm32u5-series-microcontrollers-stmicroelectronics Rv.4 , isn‘t it?
Hello forum,I need some hardware help to modify my PCB, which was developed by other people.I use STM32F103. I have one "Master"-Board and several "Slave"-Boards (up to 20) with same controller.Because of current saving reasons I need to set the cont...
