|
||||
1. Непонимание что такое "атомарный доступ" и для чего нужно "volatile" при совместной работе разных процессов/ISR с одними данными.
|
||||
|
||||
Смотрим например на usart2_getline() вызывающуюся в фоне и usart2_isr() (видимо - ISR), и думаем что будет если прерывание usart2_isr() произойдёт между строкой
|
||||
|
||||
int L = linerdy;
|
||||
|
||||
и строкой
|
||||
|
||||
linerdy = 0;
|
||||
|
||||
|
||||
|
||||
2. Алгоритм работы с приёмным потоком UART - в корне ущербный. Достаточно подумать, что будет если на большой скорости UART два символа '\n' подряд и в это время фоновая задача будет занята какой-то более-менее длительной работой (а ведь мы знаем что автор сего - ненавистник РТОС, и у него не будет повышен приоритет задаче, разгребающей UART-RX поток ;).
|
||||
|
||||
|
||||
|
||||
3. Инициализация UART (usart2_setup()) - кривая. Сначала автор программирует DMA на работу с UART, включает его, и только затем включает тактирование UART и инициализирует его.
|
||||
|
||||
Также - мультиплексор пинов переключает ноги с GPIO на UART ещё до инициализации самого UART (глитчи обеспечены).
|
||||
|
||||
Правильный порядок: 1) инит DMA; 2) инит UART; 3) разрешение DMA; 4) разрешение прерываний; 5) переключение мультиплексора ног GPIO->UART. И не забывать использовать __DMB() где надо.
|
||||
|
||||
|
||||
|
||||
4. Зачем в main() такое?:
|
||||
|
||||
const char dummy[] = "dummy text\n", err[] = "Error!\n";
|
||||
|
||||
Видимо чтобы получить как можно более тяжёлый код и занять побольше стека. Автор видимо не знает для чего нужно "static". :unknw:
|
||||
|
||||
|
||||
|
||||
5. Автор не читает мануал на используемый МК. Если бы читал, не писал бы такое:
|
||||
|
||||
USART2_ICR |= USART_ISR_CMF; // clear flag
|
||||
|
||||
Читаем описание регистра USART2_ICR и думаем: Что будет с остальными флагами кроме CMF после такой операции? Да и вообще - зачем читать из регистра если для сброса флага нужна запись в него "1"??? Тема эта уже 100500 раз обсасывалась здесь на форуме.
|
||||
|
||||
То же самое здесь:
|
||||
|
||||
DMA1_IFCR |= DMA_IFCR_CIF4; // clear TC flag
|
||||
|
||||
и в других подобных местах. Регистр DMA1_IFCR - write-only! Опять же - RTFM.
|
||||
|
||||
Наверняка ещё куча подобных багов есть - смотрел по диагонали.
|
||||
|
||||
|
||||
|
||||
6. Исходник просто наполнен "магическими" числами - стиль программирования начинающего. Плохой стиль.

Protocol have a string form, each string ends with '\n'. You should wait an answer for previous command before sending next,
|
||||
or have risk to miss all the rest commands in one packet.
|
||||
|
||||
USB commands:
|
||||
|
||||
0 - move to smallest foc value (e.g. 2.5m)
|
||||
1 - move to largest foc value (e.g. infinity)
|
||||
d - open/close diaphragm by 1 step (+/-), open/close fully (o/c) (no way to know it current status)
|
||||
f - get focus state or move it to given relative position
|
||||
h - turn on hand focus management
|
||||
i - get lens information
|
||||
l - get lens model
|
||||
r - get regulators' state
|
||||
debugging commands:
|
||||
F - change SPI flags (F f val), f== l-LSBFIRST, b-BR [18MHz/2^(b+1)], p-CPOL, h-CPHA
|
||||
G - get SPI status
|
||||
I - reinit SPI
|
||||
R - software reset
|
||||
S - send data over SPI
|
||||
T - show Tms value
