customer received part with marking 46FT8924 which isn't mentioned in datasheet (see attached). Can you provide document that says this is correct?
could you please confirm the above marking is correct one for the recieved part
I am not reading the address of M24M02 E2prom
Hi,I am using STM32F4-Discovery. I want to R/W M24M02 E2prom but not reading device address. Added code and datasheet. I tried AT24C256 E2prom other I2C devices by same code and it worked.Thanks. for(i=0; i<255; i++){ if(HAL_I2C_IsDeviceReady(&hi2c3...
HSE Crystal - choosing the right capacitor
Hi :) I am doing a project where I need a (relatively) accurate crystal. I have never used special precision crystals but my guess is a normal crystal would do. I would like though to have the best accuracy possible by laying out the PCB and choosing...
Driving 7 segment Display with STM8 - enough current?
Hi again =) I have a small project with an STM8 and I was thinking driving my 3-digit 7 segment display directly with the MCU in order to reduce the manufacturing price (I know some of these chips cost only a few cents but if I *can* do it directly ...
An example of STM8L SPI DMA regular buffer exchange between master and slave.
The example from STM8L15x-16x-05x-AL31-L_StdPeriph_Lib doesn't explain the way a regular buffer (i.e. 20 - 30 bytes of data) exchange between two MCUs in master and slave mode. Can anyone explain the steps of configuration on both sides?Now I have ST...
STM8L051 ADC Pin current consumption when HALT
Using STM8L051 ADC PD0, 3.7V~4.2V Li-Po battery, 1M+1M resistor to divde the battery voltage, 100nF capacitor to GND.If set PD0 floating input and halt, total current 40uA, if set PD0 push-pull output LOW, 10uA. But the drawback of output LOW is that...
