High-performance MCU reference design for EV/HEV battery management systems

TIDM-TMS570BMS

Overview

System example of an active cell balancing battery management system. The TMS570LS0432 microcontroller commands the EMB1402 EVM to monitor the battery cells and perform charge/discharge from one battery cell to an external 12V power supply. Users can view battery status and control battery balancing through a GUI running on the host PC.

characteristic

● Support the diagnostic function of TMS570LS0432 MCU to monitor and report TMS570LS0432 status at runtime
● TMS570LS0432 MCU configures BQ76PL455A to monitor battery voltage and check BQ76PL455A status during runtime
● TMS570LS0432 MCU analyzes data from all cells and generates valid cell balancing commands
● TMS570LS0432 MCU commands EMB1428 to perform battery balancing and monitors the status of EMB1428 and EMB1499 during runtime
● TMS570LS0432 MCU communicates with the host PC via UART emulated by the NHET module to display status and control balancing operations at runtime

2440 camera urgent problem!!
I would like to ask how to use memcpy in Display_Cam_Image of 2440 camera driver to copy P mode DMA buffer to LCD display buffer: memcpy((void *)(FRAMEBUF_BASE+ (240*pos_y + pos_x) + y*240*2),(void *)
VCA810 Program Control Problem
I recently used VCA810 as a programmable amplifier. The vca810 part is required to achieve +-40db and a bandwidth of 6MHZ. The circuit diagram I used is as follows. I started with one stage and it was
