Hello, I'm working on testing the LoRa Basics Modem V4, available in SWL2001 on github, and for now I've managed to generate the executable and download the program on the board I have, but nothing has appeared yet on The Things Network. I believe th...
Hello,I'm working on a project involving an STM32F103 and a mcp23017 port expander.I've connected the mcp23017 INTA to PA15, no pull-up or down involved.I'm able to drive the mcp23017 via I2C, no problem about that.The problem I have is detecting the...
Hello, In my STM32F407 discovery board, I want to run can communication for which firstly I set the INRQ bit CAN_MCR register then my INAK bit in CAN_MSR register is also got set by the hardware. Then for starting the can I want to clear the initiali...
Hello, I need to make 10 samples via Tim13 and PWM in STM32H7. I implemented the next script, but finally, on the oscilloscope, I saw about 50 samples every 0.1 sec. Do you know, how easily control the number of samples for Timer in stm32? #inc...
HI, For testing and debugging FMC_norflash(MT28EW01aba) with custom h753 board, I used h743i-eval example as it is for read,write,erase, hence, i could read Manufactring code in memory browser, but in live expression i see address is different, so...
I am using STM32 Nucleo-h723zg for a UART serial transmission using UART4 and UART7. I have used UART4 only in my code to test since using both was not working. Still, nothing is showing on my RealTerm serial monitor. I used STM32 Cube IDE. I don't ...
Hallo,I have a board with stm32u5. This board sends mqtt messages to a broker using a cellular modem.As os, I'm using AZURE RTOS. I'm wondering if it's better to use lwip, netxduo or stm32_cellular as a substratum. Where can I find examples of netxdu...
I an using stm32f030c8tx need to generate a pulse with a desired frequency, which can be adjusted through three different modes. The modes are as follows:Frequency remains the same.Frequency is divided by 2.Frequency is multiplied by 2.The mode is s...
I’m a newbie when it comes to flashing microprocessors. I am wondering if anyone can deduce what I may be doing wrong given the following set of facts.1. The device I was trying to repair had the symptom of halting after the progress bar instead of b...
Posted on April 23, 2018 at 18:00Hello, I'm using STM32L071RBT6 MCU, encounter a strange issue. when MCU power on, using ADC channel 0 to monitor external battery voltage, the result is OK. but once system waked up from STOP mode, ADC converter be...
