Posted on July 02, 2016 at 13:08Hi all! I'm trying to implement a usb audio sound card with stm32f4 discovery and then build an external DAC and headphone amp. I've found an excellent source code from tjaekel, which has everything I need to begin wi...
Posted on July 02, 2016 at 00:51Hi, I received a cicuit board with the STM32F427ZGT6 uC on it. I don't write code and asking for some help. I have a push-button on PG8 (normally open) and when pressed I'd like to set PB7 high. When the push-button...
Posted on July 01, 2016 at 17:07 Hello guys, I am using Keil Uvision 5.2 and cube Mx for developing STM32 MCUs. and I want to Drive a TFT-LCD which the size is 2.8 inch and it has 320*240 pixels and it has ILI9328 driver inside. I have few inform...
Posted on June 24, 2016 at 02:42I am using STM32L486RGT6 to read analog data. Programmed ADC1 in differential input mode reading from PC0 and PC1, single oversampled readings in an interrupt mode. PC0/PC1 are connected to an external OPA low impedan...
Posted on June 27, 2016 at 17:02 I am trying to transfer data to spi using timer 3 as a time base. Timer 3 works fine. Than I am using : DMA1 Stream2 Channel5 to trigger memory to SPI2->DR transfers, with no joy. //TIMER 3 CHAN...
Posted on June 28, 2016 at 03:09 Hi everyone, I am wondering how to go about setting up a varying duty cycle on an F4 board using the DMA. This is for a personal project of mine, I have asked around and believe my code does not have any g...
Posted on June 29, 2016 at 19:11I've read a few documentations from STMicro but still not sure what the actual steps to do a proper bootloading. Here is what I understand so far.1. First the bootloader firmware is already on the uC so I don't have ...
Posted on July 01, 2016 at 20:26For example, if I call the function HAL_UART_Receive_IT() with a buffer size of 16. When will the interrupt be triggered? Is it when all 16 bytes are filled up? Or when the Usart finished received all the data? Will ...
Posted on July 01, 2016 at 18:59Hi, I was wondering how the built in ADC on the STM32F4 was clocked, and how I could go about checking it's clock frequency. I know that the sample rate is configured by dividing the clock (e.g. ADC_SampleTime_480Cyc...
