Posted on August 15, 2013 at 21:35 Hello. I am using the MCU with the USB-FS library. I ran the examples successfully and I can send and receive characters via PuTTY. I've also hardcoded several messages in the program, so I can debug it easily....
Posted on August 16, 2013 at 10:18I have a medium density STM32F103TB, it does not have dedicated sound bus / I2S. What is a proper way then for me to capture PDM signal, better than reading bit by bit in the ISR at my PDM clocking rate?
Posted on March 05, 2013 at 22:57Hi, I just got a STM3220G-EVAL board. I have to connect an I2C device, but first of all I'm trying to access via I2C the LIS302DL accelerometer on board. Unfortunately, I can't find any example for that embedded devi...
Posted on August 15, 2013 at 16:36Hi, I've a problem with the SP interface. If I reset continously the uC (maybe interrupting the SPI communication would do the same) sometimes the receive buffer gets a 4-bit offset. I do communicate with 8-bit valu...
Posted on August 15, 2013 at 19:10I'm working with the STM3210E demo board and trying to modify the USB Mass Storage demo function to access only the microSD memory and not the NVRam memory too. I've removed reference to the NVRam such as initializ...
Posted on August 14, 2013 at 18:34Hi, if anyone is interested, see my problem and thanks in advance. I am using STM32F4discovery, but the problem should be general enough for all STM32 MCUs. I am just curious if it is possible to make : 1. Say, usar...
Posted on August 14, 2013 at 18:35Hello, So I tried every setup I could come up with, and had no luck. Does anyone have an example of using the Vrefint and Temp sensor ADC channels? Thanks #stm32 #internal-temperature-sensor #adc-vrefint #vrefint...
Posted on August 14, 2013 at 14:25Strange problem...Timer 2 works great when debugging. When I turn my supply off and reboot, everything is hunky dory except timer2. Any clues? TIM_DeInit(TIM2); //ENABLE CLOCKS RCC_APB1PeriphClockCmd(RCC_A...
Posted on August 14, 2013 at 18:11Hello, I am attempting to remap pins PD0 and PD1 as GPIO and whenever I try to change the pin state, it stays low. Am I setting something up wrong? Init Code: GPIO_InitTypeDef GPIO_InitStructure; /*GPIOD Ou...
Posted on August 14, 2013 at 20:21Greetings developers and hackers! I have created two spaces over on reddit for people to discuss, share, show-off, ask questions about, etc. their projects which are based on the STM32F4. You can view the posts wit...
