Posted on October 02, 2012 at 10:50Hi! I am trying to use the CS43L22 in a very simple way: only to amplify an analog signal created with the internal DACs of the STM32F4. On the Discovery board the output of DAC1 is routed to AINxx. So I create a 0...
We have a device with corrupted SRAM2 content that is failing in the field. Is clearing the SRAM2 when booting the unit using its ROM bootloader possible? I tried to read SRAM2 content by the serial port when it boots by the ROM bootloader, but it fa...
HelloI am testing new MCU's. I have a ST-Link V2 and using a STM32F401CCU6.At the start I had a simple LED flasher application however after I could not run it I started stripping everything out.This is when I saw that I can actually not even run an ...
Hi, I would like to identify the source of the interrupt that caused the MCU to wake up from Standby mode. To do this, I check the RTC_FLAG_WUTF and RTC_FLAG_ALRAF/RTC_FLAG_ALRBF flags after the system wakes up to determine the wake-up source. Howeve...
Dear ST Community member,I hope you all are doing well.We are using STM32G473VET6 and IMP34DT05TR for Audio acquisition. The PDM Microphone needs a 2 MHz clock signal to operate properly. However, we are getting an error after configuring PLLQ at 2 M...
Hello,I am using an STM32F746VGT6 with a LAN8742A PHY to implement a basic TCP server using freeRTOS + LwIP for text communications. I've attached the code below: #include "bti_tcpecho.h" #define TCP_SERVER_TASK_PRIORITY 10 BaseType_t bti_tcp_serv...
Hi I am using STM32F407 evb in which I have configured both CAN1 and CAN2 ,I am sendind CAN1(3 ids 501,502,503) and vice versa from CAN2 same I am sending but I am ble to recive all three id on CAN2 Rx but only one ID iam receving on CAN1(501) .I am ...
I am working with STM32F401RE and IHM04A1 driver board. There is timer1 channel 3 in EN-A (PA10) for IN1A and IN2A. However, there is no timer channel in EN-B which should be used for IN1B and IN2B. What should I do for the timer in EN-B, that is, PC...
Hello together, I have a question regarding the configuration of the HSE. We have a product which is running on a crystal, so we configured our HSE as "Crystal/Ceramic Resonator". In a new hardware revision our hardware team decided to use a active o...
Hi. I am a little bit confused.Why there is so many toolchains for ARM and what are the differences betwen them?Lastly i heard abot Yagarto, and also these is WinARM, arm-gcc, arm-none-eabi-gcc. Are they all the same? which toolchain should i use?I a...
