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
Posted on October 14, 2017 at 22:18How to manage: I2C_TransferHandling() for accessing high sector (>255 bit) of a 24c04 eeprom?In a selecting device I'm not capable to modify 0xA0 to 0xA1 for settings A8=1 and access to 256..512 bytes of eeprom.I'm...
Posted on January 18, 2017 at 16:20Hi,im using a STM32L476RG and want to interace an extrenal RTC via I2C.cube = 4.19.0lib L4 = 1.6.0 hi2c1.Instance = I2C1; hi2c1.Init.Timing = 0x10909CEC; hi2c1.Init.OwnAddress1 = 0; hi2c1.Init.AddressingMode = I2C_...
Posted on October 17, 2017 at 03:14I got a ST32F769NI-EVAL and trying to send serial data through UART7.I've found the right setting using PB4 as Tx and set it correctly.I use internal JTAG(not using ST-LINK) so I can use the PB4 pin as Tx.But I get...
