Hello, I built a small CAN network using CAN 2.0 transceivers. I wanted to add some FDCAN devices using classic mode. However, I seem to be having trouble just talking to the transceivers. For instance, I have an STM32L432 (Attached to a Nucleo). ...
Hi,I have designed a STM32H743IIT6 based board for controlling 35 optocouplers(4N35). These optocouplers should work at the same time(worst case). Each optocoupler will take nearly 10mA current. But I have seen in the datasheet as "Total output curre...
Is it possible to use a STM32 for something like the following:Take in a pulse, interrupting on a edge.Use this edge to generate multiple (5 or so) output pulses (only the positive edge timing needs tightly controlled timing). The output pulses might...
I want to design PLC using STM32 MCU so for that I need to extend its GPIO pins how can i do this?Adding another MCU or shift registers any other ideas?Main cpu having MCU and another io modules added is communicate with main cpu using protocol like...
I am trying to communicate with a commonly used Accelerometer form NXP (MMA8451) which uses repeated start sequence over I2C protocol, which should look like this: My problem is that the MCU doesn't seem to send a NACK at the end of transmission and ...
I am trying to read 2 channel ADC with STM32L011F4.My ADC and DMA settings in cubemx are as follows my problem is that the DMA only returns the low 8 bit of the last channel.uint16_t ADC_Reads[2] = {0}; while (1) { HAL_ADC_Start_DMA(&hadc,(uint...
Hi, I am trying to make a circuit with stm32f103c8t6 and a nrf24l0+. I attach my schematic if pcb layout needed tell me to upload that. One of the circuit work good ( the send one) the other one which is identical does not.after soldering I did check...
Various STM32 products have opamps that have a mux in front of it.Ex: STM32G4, STM32F3, STM32H7 series, etc.If I change the mux input setting using the control status register (OPAMPx_CSR::VP_SEL or VN_SEL), how long does it take for the mux to switc...
Hello Community,I've B-U585I-IOT02A. I got this with pre installed web-server with react client. Whenever I was connecting it with terminal like tera term or minicom. It ask for configuring the wifi after successful configuration, it start the simple...
