Remove CC (JHEF7DUAL)

[haslinghuis]

• confirmed by JHEMCU

Summary by CodeRabbit

• Refactor
  • Updated JHEF7DUAL hardware pin configuration: removed camera control on PB8.
  • Adjusted timer pin mappings by removing the PB8 assignment; other mappings remain unchanged.
  • Impact: Setups using PB8 for camera trigger or timing will no longer function until reconfigured to supported pins. No changes to other pins.

Walkthrough

Removed CAMERA_CONTROL_PIN macro and pruned TIMER_PIN_MAPPING by deleting the PB8 (index 8) entry in configs/JHEF7DUAL/config.h. The PA8 (index 7) mapping remains unchanged.

Changes

Cohort / File(s)	Summary of Changes
JHEF7DUAL config cleanup configs/JHEF7DUAL/config.h	Deleted #define CAMERA_CONTROL_PIN PB8. Updated TIMER_PIN_MAPPING by removing TIMER_PIN_MAP( 8, PB8 , 1, 0); kept existing TIMER_PIN_MAP( 7, PA8 , 1, 0) entry.

Learning: In STM32H743 Betaflight configurations, PB0 can use multiple timer options including TIM1_CH2N, TIM3_CH3, and TIM8_CH2N as defined in timer_stm32h7xx.c. For CAMERA_CONTROL_PIN assignments, TIM3_CH3 (timer index 3) is the appropriate choice.

Learning: In STM32F405-based flight controller configurations, timer pin mappings must be carefully analyzed for DMA stream conflicts, especially between motor timers, LED strip timers, and SPI DMA assignments. Changes to TIMER_PIN_MAPPING should include verification that all required peripherals (motors, LED strip, blackbox SPI) can coexist without DMA conflicts.

Timestamp: 2025-07-14T15:41:14.364Z
Learning: In STM32F405 configurations, PB1 typically maps to TIM3_CH4 and PC9 typically maps to TIM8_CH4. These are different timers and do not share DMA resources, so there is no conflict when both pins are used simultaneously (e.g., PB1 for LED_STRIP and PC9 for MOTOR4).

File: configs/FURYF4OSD/config.h:88-88
Timestamp: 2025-05-31T17:01:39.423Z
Learning: For STM32F4xx platforms, PB1 pin timer definitions are:
1 = DEF_TIM(TIM1, CH3N, PB1, 0, 0)
2 = DEF_TIM(TIM3, CH4, PB1, 0, 0) 
3 = DEF_TIM(TIM8, CH3N, PB1, 0, 0)
Timer instance 2 (TIM3, CH4) is the correct mapping for PB1 motor control on STM32F4xx platforms as defined in src/platform/STM32/timer_stm32f4xx.c

Learning: In STM32H743 Betaflight configurations, PA15 maps to TIM2_CH1 (timer index 2) as defined in timer_stm32h7xx.c. When used for GYRO_CLKIN functionality, it's recommended to use the macro name GYRO_1_CLKIN_PIN in TIMER_PIN_MAPPING for consistency with other pin definitions.

97-97: Approve CC removal for JHEF7DUAL config
No residual CAMERA_CONTROL_PIN or PB8 references; TIMER_PIN_MAPPING indices 0–7 are contiguous; LED_STRIP_PIN PA8 is correctly mapped.
