Hi I am using STM32L151RBT6 controller card. This was working properly also there was no issue in debugging. I am using IAR Embedded Workbench 6.4.I Added this line to my code: FnEraseEpromWord(0x080800F5,1); as because I want to erase data for this ...

I am really confused that is it necessary or not. Because if I am going to the series STM32F030 these controller doesn't have in built EEPROM memory.

I create this project in Keil using cubemx. Keil-Mdk V-5 and STM32Cubemx

So why this issue in the STM32L1 discovery board.I also uploaded images regarding the problem in the board.

As because of the cost reduction.Thank you for the answer.

Yes as because it is energy meter so its value will be continuously change.so you mean that EEPROM must be present to store values?

My question is that could I used a controller without EEPROM for my application?

I tried with 4-bit mode but it is not working in that mode also.

Here is my cubemx pin configuration. I select pin D0-D3 at PORTB pin B12-B15 and pin D4-D7 at PORTD pin D8-D11. It is cubemx generated file so I dont think there is any error.

I want to select a controller to design a energy meter. Is it necessary that controller should have EEPROM memory in built?

I am trying to run LCD 16x2 hd44780 using STM32F4 discovery board, it showed the Data at first time after that nothing display on LCD. I tried all my possible ways pleas help me out.

Hello I am using the STM32L152 discovery board but suddenly is not detected by my PC. I am also using STM32F407 Discovery board but there is not any problem like this.

Hi I am using STM32L1 series microcontroller in meter when I connect my meter to MODBUS it become hang. I don't know what is the problem.
