hudakz 0:c5e5d0df6f2a 1 /*
hudakz 16:a86f339d1c25 2 * An example showing how to use the CANnucleo library:
hudakz 0:c5e5d0df6f2a 3 *
ser1516 21:13ac27349025 4 * Two affordable (less than $3 on ebay) STM32F103C8T6 boards (20kB SRAM, 64kB Flash),
ser1516 21:13ac27349025 5 * (see [https://developer.mbed.org/users/hudakz/code/STM32F103C8T6_Hello/] for more details)
ser1516 21:13ac27349025 6 * are connected to the same CAN bus via transceivers (MCP2551 or TJA1040, or etc.).
ser1516 21:13ac27349025 7 * CAN transceivers are not part of NUCLEO boards, therefore must be added by you.
hudakz 6:7ff95ce72f6d 8 * Remember also that CAN bus (even a short one) must be terminated with 120 Ohm resitors at both ends.
hudakz 6:7ff95ce72f6d 9 *
hudakz 16:a86f339d1c25 10 * For more details see the wiki page <https://developer.mbed.org/users/hudakz/code/CANnucleo_Hello/>
hudakz 6:7ff95ce72f6d 11 *
hudakz 17:18d4d0ff26a6 12 * NOTE: If you'd like to use the official NUCLEO boards comment out line 22
hudakz 6:7ff95ce72f6d 13 *
hudakz 6:7ff95ce72f6d 14 * The same code is used for both NUCLEO boards, but:
hudakz 0:c5e5d0df6f2a 15 * For board #1 compile the example without any change.
ser1516 21:13ac27349025 16 * For board #2 comment out line 23 before compiling
hudakz 4:ccf4ac2deac8 17 *
hudakz 6:7ff95ce72f6d 18 * Once the binaries have been downloaded to the boards reset board #1.
hudakz 0:c5e5d0df6f2a 19 *

Crazyaboutmachines 32:977a1b5728e4 42 Processo de carregamento:
Crazyaboutmachines 32:977a1b5728e4 43 (1) Desconectar carregador da rede AC
Crazyaboutmachines 32:977a1b5728e4 44 (2) Conectar carregador as baterias
Crazyaboutmachines 32:977a1b5728e4 45 (3) Conectar carregador da rede AC(talves mais pratico ter botao?)
Crazyaboutmachines 32:977a1b5728e4 46 (4) Carga iniciase automaticamente(?) até uma tensao maxima de 4*27=108V
Crazyaboutmachines 32:977a1b5728e4 47 (5) Para desligar carregador desconectar da rede AC
Crazyaboutmachines 29:3af76325f86a 48
Crazyaboutmachines 29:3af76325f86a 49 Tarefas:
Crazyaboutmachines 32:977a1b5728e4 50 -ver celulas em que o balanceamento nao esta a funcionar
Crazyaboutmachines 32:977a1b5728e4 51 -ver porque as tensões nao se estão a actualizar (por a fazer display da soma das tenções)
Crazyaboutmachines 32:977a1b5728e4 52 -ver porque o charger nao responde as mensagens CAN
Crazyaboutmachines 32:977a1b5728e4 53
Crazyaboutmachines 29:3af76325f86a 54 -acabar de formatar o codigo do BMS encurtando interrupts, programando todas as BMS's e aumentando fiabilidade, etc
Crazyaboutmachines 29:3af76325f86a 55 -ligar carregador e ver que tensoes de CAN e de saida manda cá para fora+ ver que mensagens
Crazyaboutmachines 32:977a1b5728e4 56
Crazyaboutmachines 32:977a1b5728e4 57 Atenção:
Crazyaboutmachines 32:977a1b5728e4 58 -obrigatorio conectar e desconectar as baterias do carregador quando este esta desconectado da rede AC
Crazyaboutmachines 32:977a1b5728e4 59 -em caso de algum problema desligar primeiro ficha da redeAC do carregador e depois desconectar ficha das baterias
