Posted on October 12, 2017 at 12:21HiI am trying to probe data going between the STM32F407 MAC and LAN8720A. I have a 50MHz clock from MCO1 to the PHY and seems to be working as the LED's are recognizing the network. I believe the clock signal is id...
Posted on October 17, 2017 at 15:11We have project generated in STM32CubeMX v.4.21.0 based on STM32F407VETx MCU. This project use USB_OTG_HS to communicate with host computer. When we write program to flash at origin value ORIGIN = 0x8000000 all wo...
Posted on October 17, 2017 at 15:08Hi, I'm trying to read data from mems sensor with an stm32f042 using spi, but unfortunately the spi does not seem to be working. I've used CubeMX to configure the project. The LSM6DSL_Config() function is the first...
Posted on October 17, 2017 at 14:53Big fan of the STM32 Workbench. Really top notch work that makes my work much easier. Thanks.Wondering though. Have some larger applications that I would love to throw at some bigger silicon. Has anyone successfull...
Posted on October 17, 2017 at 14:27Hello all, I am using the X-CUBE-BLE1 example project in my custom board. It is working perfectly. Instead of the fake data, I have linked with the real temparature sensor data which i am getting over SPI ADC.I am ...
Posted on October 17, 2017 at 13:19I use STM32L476.Seems both EXTI 19 and RCC NMI IRQ are related to CSS (clock security interrupt), can someone tell me what's the difference?
Posted on October 16, 2017 at 17:14Working with the STM32L052C8 using the HAL commands. I'm using the 'HAL_Delay()' command which is meant to be a delay in ms but I'm measuring HAL_Delay(1); to be 15ms. Checked with the data sheet and it says to hav...
Posted on October 17, 2017 at 10:31Hi.I'm not sure whether one IRQ handler can handle multiple ports.For example, If I made one EXTI3_IRQHandler(), then I want to connect external interrupts PA0, PA1, PA2, PA3 to EXTI3_IRQHandler().Is this possible ...
Posted on October 13, 2017 at 14:05I'm using stm32 Workbench with CubeMX and STM32F4DISCOVERY with STM32F407VG microcontrollerI setup everything in CubeMX as default:- RCC-> Crystal/Ceramic Resonator- SYS->SerialWire with SysTic Timebase Source- USB...
Posted on October 17, 2017 at 06:33HelloI am using STM32F746-Discovery.I run USB in high speed mode.Internal DMA is enable.But, if I use ICache and DCache my host is't initialization.Who will tell me what the problem is?What am I doing wrong?Alex
