Posted on November 03, 2017 at 16:43Hi, I am using Keil and STM32F769I-Eval board.I try to readout a sensor with an external ADC (AD7980). The signal I try to convert runs with 200kHz.I generate with a timer every 5us an interrupt. With the interrup...
Posted on November 04, 2017 at 20:18I'm using my stm32f446 nucleo to build a weather band radio with SAME decoder. If the weather is good, the only emergency alert broadcast is the required weekly test. Debugging my code when I have only one oppor...
Posted on November 02, 2017 at 22:28 I am having some debugging issues with Keil uVision5 eval (free) version. Now the STM32F030F4P6 has 16K bytes, and when I compile my program, it is approaching the memory limits. Below is the code size: Progra...
Posted on November 03, 2017 at 06:51Hello,I am using an STM 32 F401 Nucleo and i want to send numbers from PC via UART.For example I need to set the frequency and amplitude.Can some one help me to provide the code?Thank you in advance.
Posted on November 04, 2017 at 11:17I want to transfer some data between two microcontrollers via 16 lines of data and one clk line.(Based on STM Application note AN4666 ''Parallel synchronous transmition using GPIO and DMA'').I use two STM32f407 fo...

Posted on November 03, 2017 at 08:07Sometimes without any reproduceable reason my project with STM32F767 does not power up. If this occurs Read Out Protection is set (which I definitely do not have done) and Option Bytes are scrambled: BOOT_ADD0 and...
Posted on November 04, 2017 at 09:15I am using the stm32f746-discovery board with the ov9655. I downloaded a program from the internet and programed the MCU using st-link utility(https://embeddedintelligence.wordpress.com/projects/stm32f746ngh6-disc...
Posted on July 27, 2016 at 02:33I have been trying to get the burst DMA working across Timers on the STM32F334 without success. The reference manual has; The burst DMA mode is permanently enabled (there is no enable bit). A burst DMA operation is st...
