Right now, I am able to get I2C data from sensor. I have generated PWM signal separately with TIM_CH2. But I have no idea how to generate pwm from I2C signal. So, basically I need to control amplitude of pwm from i2c signal. I am using NUCLEO-L011K4 ...
Hello,I don't find on the STM32H730ZB datasheet a clear information about the maximum current output for the DAC ( with or without a OPAMP in follower). I plan to drive a LED from 100µA to 10mA maximum.Today, I have an externaI op-amp & mosfet but I ...
I'm trying to get a STM32Cube project compiled using arm-none-eabi-gcc and a Makefile. The FW builds without problems.but when I boot the MCU i get stuck in Hard Fault. Any ideas what could be wrong?Reset_Handler: ldr sp, =_estack /* set s...
Hello everybody,I'm using STM32CubeIDE version v1.7.0 and Firmware package FW_H7 v1.9.0. The tests were made on a Nucleo H745ZI (dual-core MCU).Test 1:Enabled RTC for the M7Configured RTC Wakeup parametersEnabled RTC Wakeup interrupt on NVICResult: T...

I have difficulties with the following scenario:There is a big buffer of bytes in DTCM memory. The buffer should be transmitted out through UART or SPI. I'm looking for solution, where software only configures the transaction, and then the whole proc...
Hello, I am currently trying to figure out, how to send continuos information via CAN.When threre are only a few nodes Connected to the network, everything is fine, bus as soon as the overall busload is bigger than ~70% then the STM32 MCU stops trans...
I am working on a startup, outsourcing AI and IoT focused on embedded systems, from South America (Argentina) to the United States, we are looking for a beachhead market, I have a few questions, any advice will be very appreciated:- What ecosystems, ...
