I am trying to use ADC with 2 channels and DMA, but I only get 1 reading before the overrun bit gets set. Also the 1 reading is wrong, I am expecting a value of approx 2100, but I am getting around 70. I can see in the hadc->DR that the value are cor...
Hi !i'm trying to write a driver, to interface the "ADS1220" device with STM32F103RBT6, using SPI,i would like to assign each pin of the MCU SPI (PA4, PA5, PA6, PA7) with its corresponding pin of ADS1220 like this : using macros#define ADS_CS PA4 // ...
Hi,I am facing some issues while jumping from main application to the last locations(0x0801C000) of the flash memory, where IAP application (customized) is located.The controller used is STM32F072.(128kb flash,Cortex-M0).The main application code pl...
__WFI works beauty. But I want more. Behold:void vApplicationIdleHook() { __WFI(); my_own_code(); // on wake, this will be executed *after* the intr handler :( }Upon every wake from WFI, I want to execute my own code immediately: ie. bef...
I hope this question is not off topic.I have a board running httpd using a STM32F407. The web server is running CGI and SSI. The cgi file is named index.shtml and is called when the browser first accesses the website.In the SSI part of the code I pop...
Hello!I am trying to use the NOR flash module on the STM32L4R9I-EVAl board. I've been able to use the ST-provided example without issue, but in trying to build a project through CubeIDE, I've run into an intermittent fault. Sporadically, my writes to...
I'm getting a lot of noise from my STM32 design, which is just supposed to be direct line-in/out I2S with DMA.I'm feeding in a 440Hz sine wave to my CS5343 A/D converter:And this is the output I'm seeing from my CS4344 D/A converter:If I zoom out a b...
Hi, i have some rather strange problems with my custom with an STM32F103C8 mcu on it. It is programmed via an Nucleo ST Link v2/1 and it works fine most of the time. I can load some test sketches on it via Platform IO or STM32CubeIde. But after a fe...
Hi, anyone know there is a register that can count the pulse directly on STM32H7?I know there is a timer in capture mode, it can generate interrupt when detected edge high or low. But this counter does count the period time only, does not count how m...
Iam working in STM32F723ZE controller I have downloaded flash loader demonstrator, but it does not have map file stm32f723ze controller.Does any one have the correct map file for this device, Can you please share this.I have created one but doesn't w...
