Posted on August 04, 2014 at 12:22Dear all, We are using DMA connecting with an ADC though SPI in circular mode. ADC results will be loaded into array1[320] and arrary2[320].My question is sometimes I need to stop DMA transmission and restart it lat...
Posted on August 06, 2014 at 10:46 I have tested EEPROM emulation code for STM32F4 recently. It works fine. Now I want to save some data written the following code for saving some floats. For conversion of floatto int32_tand again conve...
Posted on August 06, 2014 at 23:31Hi everyone,In my project, i need to use iwdg. I use 2 iwdg init function. Prescaler is 256 and reload is 15seconds for the first one.Prescaler is 32 and reload is 1.45seconds for the second one.Both of them is work...
Posted on August 01, 2014 at 15:14Hello,I'm trying to get the USB Virtual COM port loopback example project work on STM32F102.When the USB is connected, the PC says ''Unkown device connected'' with VID 0 PID 0 so obviously it's not enumerated.On the...
Posted on August 06, 2014 at 09:13Hello. My system happened to be in hardfault state. In case of hardfault state, Is it possible to reset by watchdog? Thanks ahead Kevin #iwdg-wwdg
Posted on July 10, 2014 at 11:16Hi all, I am currently using stm32 discovery board. I am new in this field so I need some help. 1. Can some one tell me that is it possible to read whole sector(s) of Flash memory at once, and how it can be done? 2. W...
Posted on July 10, 2014 at 09:11HiI have stm32f4 discovery board, first I could program the board but now It does not work. all jumpers are fine and I'm trying to run a sample program such as LED toggle. I checked the GPIO configuration and I just c...
Posted on July 18, 2014 at 21:18Hi, I'm getting the following build error, it appears ''IMAGE_SetPNG'' is not defined in STemWin library. Building configuration: Project - STM324x9I_EVAL_MB1046 Updating build tree... kohler_windowDLG.c Linking ...
Posted on June 18, 2014 at 08:49 Dear Community! I'm using DMA to transfer the ADC1 results (100 consecutive data) to some incremented memory address. DMA is in Normal mode (not circular), it is transfering 100 data, repeatedly over time....
Posted on July 16, 2014 at 10:45I'm trying to understand how to build a buffered serial handler using DMA. I currently have an interrupt driven handler, that adds characters received to a circular buffer, but due to the lack of a FIFO on the USARTs,...
