S2-LP: Doppler effect due to tranciever moving at a speed 1 m/s
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 need to make connection between two STM32 Nucleo 64 via I2C. I followed an example in STM32Cube\Repository\....\I2C_TwoBoards_ComDMA I configurbased on this example and connected SDA, SCL but nothing is transferred. I am cant solve the problem.
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_...

SPIRIT1. Any ideas why I might see double the expected frequency deviation?
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...
How do you JTAG chain the Bluenrg-2 232 and STM32L4R5VIT 100pin package?
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...
ST2378ETTR only one power supply with OE low => output high
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
BLE stops advertising when bonding is enabled and rebooted. I think the problem is in stack initialization. How to deinitialize the BLE stack before rebooting.??
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...
