Hi!In my situation i have two boards with S2-LP (868Mhz): one for transmit data and one for recieve. The reciever is stationary located and doesn't move. The transmitter moves back and forth at a speed 1 meter/second.My question is: should i bother a...
I configure the I2C as follows:hi2c1.Instance = I2C1; hi2c1.Init.ClockSpeed = 100000; hi2c1.Init.DutyCycle = I2C_DUTYCYCLE_2; hi2c1.Init.OwnAddress1 = I2C_ADDRESS; hi2c1.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT; hi2c1.Init.DualAddressMode = I2C_...
As I am doing debugging in STM32L072CZ using ST Link/V2 by STM32 ST-Link Utility software. But I getting error message as Connect Under Reset and I have tried under all mode but same error has been repeated. How can I solve this error and I also atta...
Hello,We are using the SPIRIT1 with a 50MHz crystal (as part of an SPSGRFC-433 module); I've configured it to MSK, with a base frequency of 433.175MHz, a data rate of 250kBaud, which leads to a configured frequency deviation of ±62.5kHz. I've set a b...
I am building a board that will use both the STM32L4R5VIT 100pin package and Bluenrg-2 232. I would like to JTAG chain the two processors so that I can use my Segger Jlink to debug both processors from the same debug connector. The pins to use for JT...
Hello,In case I have the following case:Vcc=3.3V, VL=OE=0V, I/OVL1 = 0VWhy is I/OVCC1 at 3.3V with OE=0V?Best regardsMich
Initially when bond is disabled, BLE works fine. But when bonding is enabled through AT Commands and board is reset, I get error like "Error in aci_gap_set_discoverable(): 0x42". I am storing the Bond status in nvm. Is nvm making the issue? I suspect...
Hi all,Where can I find code example for STM32F429zi ram drive codeI see FatFS and other examples, but no ram-drive FatFS exampleI need to open a device over USB to be recognized by the PC HOSTThanksEli
Hi! Is anybody have a schematic with a BALF-SPI2-02D3 + SAW FILTER? Is this wiring will be good?
Hello I'm try to connect 1 master and 2 slave, but failed, I use stm32f427VI, and use Truestudio for programing, thanks for your help./* SPI4 init function */ //SLAVE1 static void MX_SPI4_Init(void) { /* SPI4 parameter configuration*/ hspi4.Ins...
