## Creating a .ioc file from scratch If you make a new .ioc file, ex. for a different MCU, follow this guide:
**MISC**
* DMA stream mem2mem, Mode: Normal, Size: Word, increase only dest address. * Buzzer: GPIO Output, User label: BUZZER, No pull * Wake: GPIO Input, User label: WAKE, No pull **CRC**
* Enabled, default settings **ENCODER**
* Rotatory encoder right: GPIO INPUT, name: ENC_R, no pull * Rotatory encoder left: GPIO INPUT, name: ENC_L, no pull * Rotatory encoder button: GPIO INPUT, name: ENC_SW, no pull **OLED**
* Oled CS: GPIO Output, name: OLED_CS, no pull * Oled DC: GPIO Output, name: OLED_DC, no pull * Oled RESET: GPIO Output, name: OLED_RST, no pull **SOFTWARE SPI/I2C** (If used)
* OLED CLOCK Label: SW_SCL No pull Speed: high * OLED DATA signal Label: SW_SDA No pull Speed: High **HARDWARE SPI** (If used)
* GPIO Settings * Oled SPI CLOCK No pull Speed: High * Oled SPI MOSI No pull Speed: High * Parameter settings Mode: Half-Duplex master or master transmit only NSS: Disabled Data size: 8 MSB First Prescaler: Adjust for max speed, usually the limit is 18Mbit Clock Polarity: Low Clock Phase: 1 Edge CRC Calculation: Disabled NSSP Mode: Disabled NSSP SIgnal Type: Software * DMA Settings SPIx_Tx Direction: Memory to peripheral Piority: Low DMA request mode: Normal Data width: Byte in both * NVIC Settings DMAx channel interrupt enabled SPIx global interrupt disabled **HARDWARE I2C** (If used)
* GPIO Settings Oled I2C CLOCK No pull Speed: High Oled I2C DATA No pull Speed: High Parameter settings I2C Speed Mode: Fast mode or Fast-mode Plus (The fastest the better). (Try lower speeds if it doen't work) I2C Clock Speed: 100KHz...1MHz Slave features: Don't care DMA Settings I2Cx_Tx Direction: Memory to peripheral Piority: Low DMA request mode: Normal Data width: Byte in both NVIC Settings DMAx channel interrupt enabled I2Cx global interrupt disabled **ADC**
* GPIO config NTC pin label: NTC (Don't care) V Supply pin label: VINPUT (Don't care) VRef pin label: VREF (Don't care) Iron Temp pin label: IRON (Don't care) * Parameter settings Select channels assigned to the used inputs Clock prescaler: Asynchronous clock mode Resolution: 12 bit resolution Data Alignment: Right alignment Scan Conversion Mode: Forward Continuous Conversion: Enabled DMA Continuous Requests: Enabled End Of Conversion Selection: End of Single Conversion Overrun behavior: Overrun data preserved Low Power Auto Wait: Disabled Low Power Auto Power Off: Disabled Sampling time: Don't care, adjusted within the program. External Trigger Conversion Source: Don't care, adjusted within the program. External trigger Conversion Edge: None Watchdog disabled **IMPORTANT: Configure in board.h the order of the channels and set their labels accordingly!** The ADC channel order goes from 0 to 15 (unless otherwise set in regular config), skipping the disabled channels. You must define the ADC channels in these lines: #define ADC_CH_1ST ADC_CHANNEL_1 // First used channel: CH1 #define ADC_CH_2ND ADC_CHANNEL_4 // Second used channel: CH4 #define ADC_CH_3RD ADC_CHANNEL_7 // Third used channel: CH7 #define ADC_CH_4TH ADC_CHANNEL_9 // Fourth used channel: CH9 Also, they must be adjusted depending on the signal connected to them: #define ADC_1st VREF // First used channel measures VREF #define ADC_2nd NTC // Second used channel measures NTC #define ADC_3rd VIN // Third used channel measures VIN #define ADC_3rd TIP // Fourth used channel measures TIP Set the number for active ADC channels: #define ADC_Num 4 // Number of active channels Except the tip ADC input, all the others can be enabled or disabled: #define USE_VREF #define USE_VIN #define USE_NTC Power limit will not be available if VIN is disabled. When disabling NTC, ambient temperature is internally set to 35ºC. * DMA settings Pheripheral to memory Mode: Circular Data width: Half word on both. * NVIC Settings DMAx channel interrupt enabled. ADC and COMP*** interrupts disabled **DELAY TIMER**
* Base timer Internal clock Internal clock division: No division Auto-reload preload: Enable Master/Slave mode: Disable Trigger event selection: Reset Prescaler: Don't care, it's adjusted within the program. It asumes the timer runs at CPU speed Some timers may take haf the clock speed, depending on the bus! In that case use #define DELAY_TIMER_HALFCLOCK in board.h! Check the Clock config in CUBEMX! Period: Don't care, it's adjusted within the program NVIC settings: General enabled **PWM**
* GPIO User label: PWM Mode: TIMxCHx(N) ("x" and "N" depends on the selected pin) * TIMER Select timer assigned to the pin Check Activated Select channel assigned to the pin Mode: PWM Generation. Select CHx(N), as assigned to PIN. Ensure to select "N" if the pin has it! Prescaler: Don't care, it's adjusted within the program. It asumes the timer runs at CPU speed. Some timers may take haf the clock speed, depending on the bus! In that case use #define PWM_TIMER_HALFCLOCK in board.h! Check the Clock config in CUBEMX! Period: Don't care, it's adjusted within the program. Pulse: Don't care, it's adjusted within the program. NVIC settings: Depending on the timer type, enable TIMx "Capture compare" if available, else use "Global interrupt".
