Page 4: Product Overview
I. Product Overview 1.1 Product Introduction MBL series testing kits are designed to help users quickly evaluate Ebyte's new generation of package-compatible wireless modules. Most of the pins on the board have been led out to pin headers on both sides, and developers can easily connect various peripheral devices through jumpers according to actual needs. - Page 5 成都亿佰特电子科技有限公司 MBL 评估套套件用户手册 Definition Function Description Module power supply pin. It needs to be shorted with pin 2 to supply power to the module. 3.3V 3.3V power pin 3.3V 3.3V power pin MCU power supply pin. It needs to be shorted with pin 3 to power the MCU.

When switching the workspace, different macro definitions will be used to switch the driver files of different modules. When the "Exclude from build" attribute of "Drivers/Ebyte/RF" is changed, the target module driver folder is selected to participate in the compilation process. -

成都亿佰特电子科技有限公司 MBL 评估套套件用户手册 2.3 Main function main.c is the main function entry. The demo function process is simplified as follows: Item Description Key Function When a button is pressed, the command data is sent wirelessly. Essentially sending a specific string "ping" and expecting a "pong" in response. - Page 10 成都亿佰特电子科技有限公司 MBL 评估套套件用户手册 replace it with the same type of function Go_xxxxx(). Sending mode When calling the sending function, the underlying driver actually switches the module into standby mode first, and usually completes the modulation parameter configuration in this mode, such as frequency, power, frequency offset, etc.

成都亿佰特电子科技有限公司 MBL 评估套套件用户手册 Programming Description Document ebyte_core.h A module structure is defined, the basic functions are abstracted, and the functions of the underlying module will be bound to the structure. When used in simple sending and receiving applications, there is no need to understand the underlying working details of each module, and the data can be sent and received by directly calling the abstracted function. - Page 12 成都亿佰特电子科技有限公司 MBL 评估套套件用户手册 underlying modules, you can also directly remove the ebyte_core.c/h file, and there is no strong coupling between the layers. ebyte_exx.c It is a specific module driver file, which is generally packaged and does not need to be modified by the user. It only needs to consider how to input and output data from this "box".
- Page 13 成都亿佰特电子科技有限公司 MBL 评估套套件用户手册 situations. ebyte_exx.h Some conventional modulation parameters are defined, generally do not need to be modified, you can adjust them by yourself. Note, please understand the instructions in the comments when modifying. There is a range check for parameters in the module driver, and wrong modulation parameters will cause initialization failure.
