I have a Demo application based on the Audio Playback and record example program . This example defaults to using the onboard digital mics. I need to use the analog mic/CN6 Line in (blue) jack . I made changes to use the INPUT_DEVICE_ANALOG_MIC. T...
how to store the data in specific memory location by using Linker script i found this one in tool how to use this one can any one tell me.ENTRY(Reset_Handler)/* Highest address of the user mode stack */_estack = 0x20009000; /* end of "RAM" Ram type m...
Hello All,I was wondering if it is possible to clock another STM32 MCU (STMF031) using the single existing crystal oscillator that is currently clocking the main MCU (STM32F334). It could really save me space, power, cost and another clocking source ...
My stm32 mcu is a i2c slave device. When master sends the address on the bus, I want stm32 to respond with a known byte upon address match. How can I do that?I want to send different type of data with different size to the stm32 slave. How can I make...
Questions about STM32F479BIT6If the MIPI circuit is unused andThe following pins are NC,pull-up,pull-downWhich terminal treatment should I use?Target Terminals119/120/121/122/122/122/124/124/125/126/127/128/
I am learning on using the STM32L431CC FLASH memory to store data after the microcontroller loses power. From compiling through Keil, I get:Program Size: Code=34316 RO-data=1228 RW-data=364 ZI-data=1908From the above, Is it correct that only 35Kbytes...
I'm using 'stm32f103rc'.I connected the button to the GPIO PIN.If the button is still pressed, the HIGH signal will continue to occur.So, how do you detect how long the HIGH signal has been pressed?Because when the button is pressed for more than 0.5...
On my stm32g0 mcu there is no eeprom. So, I am using internal flash to save one byte user data to retain it between power cycles.I am doing it the following way,Add Data section in memory in the linker scriptMEMORY { ...... DATA (xrw) : ORIGIN =...
Hi there,I'm designing an application with an STM32L412K8 and I don't use ADC, OPAMP or COMP. The datasheet (DS12469) says:VDDA shall be 0 to 3.6 V if ADC, OPAMP, COMP is not used (general operating conditions table 21).When the functions supplied by...
