STM32 for high resolution delays
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...
How to increase GPIO on any STM32 MCU?
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...
Trying to use Repeated Start I2C on STM32F103RCT6 but the MCU doesn't send a NACK at the end.
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 ...
Resolved! STM32L0 multi-channel ADC reading has DMA problem
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...
stm32f103c8t6 short cuts after programming!
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...
Resolved! Switching time for mux on Opamp
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...
Resolved! How to flash STM32U5( B-U585I-IOT02A ) with web server demonstration.
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...
hi I would like to know how to read a mcu st arm sta2062a
it is a processor that is located on a blue & me control unit from fiat
FMC peripheral memory
How far from FMC shall we place memory device. I have stack-up design(3 boards) in which MCU is on top board and FPGA is on bottom board. I need to map FPGA to FMC. Are there design consideration for routing FMC signals for such board to board commun...
