Posted on January 06, 2016 at 14:08Good day! I get a picture with the camera in the RGB565 format, using DMA. Full frame normally captured and stored to the external SRAM (16-bit word). When I try using a hardware crop of DCMI to capture strip heigh...
Posted on January 06, 2016 at 12:58Hello there, I have a conceptual question regarding STM32F4 and external SRAM connected to it. Is it possible at any point, to work with external sram, as it would be internal, in regard to programming flow? What I...
Posted on January 06, 2016 at 13:35I'm looking at the STM32F446xx datasheet and on page 78 it specifies a minimum ''VDD rise time rate'' of 20uS/V, whereas the maximum is infinity. I assume this means using a slower supply with a longer rise time, e...
Posted on January 04, 2016 at 18:12I would like to point the attention of ST to the problem they have in the CubeMX generated code.In HAL_StatusTypeDef HAL_I2S_DMAStop(I2S_HandleTypeDef *hi2s) function the procedure described in 26.6.4 I2S master mo...
Posted on January 06, 2016 at 12:26Hi We have STM32F429 based board. We are using freeRTOS 8.2.2. Now we would like to enable freeRTOS-MPU. I have gone through link http://www.freertos.org/FreeRTOS-MPU-memory-protection-unit.html Does anyone guid...
Posted on January 06, 2016 at 11:46Hi, I'm developing a data logger using STM32L053R8. I'm preparing the custom board with some sensors. I would like to use a On/Off button to my board. I wondering to which pins and how can i implement this hardware...
Posted on January 05, 2016 at 10:36Hi , I have the STM3240G-Eval board and currently I'm working on a project which in it I'll need to display text in the LCD. I searched the internet for some informations to configure STM3240G-EVAL LCD (MB785 driv...
Posted on January 06, 2016 at 11:06 I am using a STM32F302 custom made board. I have configured my filter banks as follows to configure message received from controller: uint16_t STID4 = (0x02 << 9) | (0x18 << 3) | 0x06; //0...
Posted on November 30, 2015 at 08:41Hi all, I'm trying to run the example Udp Echo Server with raw API from LwIP (included in the cube 1.9.0) on a STM32F4 discovery board, with a STM32F4DIS-BB extension board. Unfortunately the code doesn't seem to ...
Posted on December 31, 2015 at 05:16Hi guys,I used AC6 system workbench to development STM3210C_eval evaluation board.Now I try to use Fatfs to get SD card Capacity->res = f_getfree(''0:/'', &fre_clust, &fs);In debug mode, I get:Name : res Details:F...
