STM8AF52AATCY如何让控制器进入睡眠模式

问答对人有帮助，内容完整，我也想知道答案 0 尊敬的先生/女士，如何让控制器进入睡眠模式。您能否给我信息或发送给我任何源代码链接。在这里，我使用halt（）进入睡眠状态;禁用外围设备的模式，但我在想是否还有其他配置需要做。请建议我解决这个问题。以上来自于谷歌翻译以下为原文 Dear Sir/Madam, How to make controller goes into sleep mode. Can you please give me information or send me any source code link. Here, I am making into sleep using halt(); mode with disabling the peripherals but I'm thinking that Is there any other configuration need to do. Kindly, suggest me to solve this issue. 0

答案对人有帮助，有参考价值 0 尊敬的先生/女士，现在我完全停止了控制器。但是当它处于暂停模式时，如果触发任何GPIO外部中断意味着它会唤醒，但是当我发送CAN标识符时，它就不会被唤醒。按照暂停模式下的数据表，如果CAN_RX中断到来，它应该被唤醒。那么，在进入暂停模式之前，能否指导一下我需要为CAN配置什么初始化。在这里我添加了CAN_Config（）;功能。 void CAN_Config（void） { CAN_InitStatus_TypeDef status = CAN_InitStatus_Failed; / 过滤参数 / CAN_FilterNumber_TypeDef CAN_FilterNumber; FunctionalState CAN_FilterActivation; CAN_FilterMode_TypeDef CAN_FilterMode; CAN_FilterScale_TypeDef CAN_FilterScale; uint8_t CAN_FilterID1; uint8_t CAN_FilterID2; uint8_t CAN_FilterID3; uint8_t CAN_FilterID4; uint8_t CAN_FilterIDMask1; uint8_t CAN_FilterIDMask2; uint8_t CAN_FilterIDMask3; uint8_t CAN_FilterIDMask4; / * Init参数* / CAN_MasterCtrl_TypeDef CAN_MasterCtrl; CAN_Mode_TypeDef CAN_Mode; CAN_SynJumpWidth_TypeDef CAN_SynJumpWidth; CAN_BitSeg1_TypeDef CAN_BitSeg1; CAN_BitSeg2_TypeDef CAN_BitSeg2; uint8_t CAN_Prescaler; / * CAN注册init * / CAN_DeInit（）; / * CAN init * / CAN_MasterCtrl = CAN_MasterCtrl_AllEnabled; // CAN环回模式JNa // CAN_Mode = CAN_Mode_LoopBack; CAN_Mode = CAN_Mode_Normal; / * CAN_SynJumpWidth = CAN_SynJumpWidth_1TimeQuantum; CAN_BitSeg1 = CAN_BitSeg1_5TimeQuantum; CAN_BitSeg2 = CAN_BitSeg2_2TimeQuantum; CAN_Prescaler = 4; * / CAN_SynJumpWidth = CAN_SynJumpWidth_1TimeQuantum; CAN_BitSeg1 = CAN_BitSeg1_8TimeQuantum; CAN_BitSeg2 = CAN_BitSeg2_7TimeQuantum; CAN_Prescaler = 8; / * 500kbit / s * / status = CAN_Init（CAN_MasterCtrl，CAN_Mode，CAN_SynJumpWidth，CAN_BitSeg1， CAN_BitSeg2，CAN_Prescaler）; / * CAN过滤初始化* / CAN_FilterNumber = CAN_FilterNumber_0; CAN_FilterActivation = ENABLE; CAN_FilterMode = CAN_FilterMode_IdMask; CAN_FilterScale = CAN_FilterScale_32Bit; CAN_FilterID1 = 0; CAN_FilterID2 = 0; CAN_FilterID3 = 0; CAN_FilterID4 = 0; CAN_FilterIDMask1 = 0; CAN_FilterIDMask2 = 0; CAN_FilterIDMask3 = 0; CAN_FilterIDMask4 = 0; CAN_FilterInit（CAN_FilterNumber，CAN_FilterActivation，CAN_FilterMode， CAN_FilterScale，CAN_FilterID1，CAN_FilterID2，CAN_FilterID3， CAN_FilterID4，CAN_FilterIDMask1，CAN_FilterIDMask2， CAN_FilterIDMask3，CAN_FilterIDMask4）; / 启用Fifo消息等待中断 / / 消息接收由CAN_RX ISR /完成 CAN_ITConfig（CAN_IT_FMP，ENABLE）; 在这里，我怀疑我的配置，需要改变什么配置。以上来自于谷歌翻译以下为原文 Dear Sir/Madam, Now I did controller into halt completely. But when it's in halt mode if any GPIO external interrupt is triggered means it wakes up, but when I will send the CAN Identifier then It's not waking up. As per data sheet in halt mode if CAN_RX interrupt comes it should wake up. So, can you please guide to me what initialization I need configure for CAN before entering into the halt mode. Here I added CAN_Config(); function. void CAN_Config(void) { CAN_InitStatus_TypeDef status = CAN_InitStatus_Failed; /* Filter Parameters / CAN_FilterNumber_TypeDef CAN_FilterNumber; FunctionalState CAN_FilterActivation; CAN_FilterMode_TypeDef CAN_FilterMode; CAN_FilterScale_TypeDef CAN_FilterScale; uint8_t CAN_FilterID1; uint8_t CAN_FilterID2; uint8_t CAN_FilterID3; uint8_t CAN_FilterID4; uint8_t CAN_FilterIDMask1; uint8_t CAN_FilterIDMask2; uint8_t CAN_FilterIDMask3; uint8_t CAN_FilterIDMask4; / Init Parameters/ CAN_MasterCtrl_TypeDef CAN_MasterCtrl; CAN_Mode_TypeDef CAN_Mode; CAN_SynJumpWidth_TypeDef CAN_SynJumpWidth; CAN_BitSeg1_TypeDef CAN_BitSeg1; CAN_BitSeg2_TypeDef CAN_BitSeg2; uint8_t CAN_Prescaler; / CAN register init / CAN_DeInit(); / CAN init / CAN_MasterCtrl=CAN_MasterCtrl_AllEnabled; //CAN Loop Back Mode JNa //CAN_Mode = CAN_Mode_LoopBack; CAN_Mode = CAN_Mode_Normal; /CAN_SynJumpWidth = CAN_SynJumpWidth_1TimeQuantum; CAN_BitSeg1 = CAN_BitSeg1_5TimeQuantum; CAN_BitSeg2 = CAN_BitSeg2_2TimeQuantum; CAN_Prescaler = 4;/ CAN_SynJumpWidth = CAN_SynJumpWidth_1TimeQuantum; CAN_BitSeg1 = CAN_BitSeg1_8TimeQuantum; CAN_BitSeg2 = CAN_BitSeg2_7TimeQuantum; CAN_Prescaler = 8; / 500kbit/s / status = CAN_Init(CAN_MasterCtrl, CAN_Mode, CAN_SynJumpWidth, CAN_BitSeg1, CAN_BitSeg2, CAN_Prescaler); / CAN filter init / CAN_FilterNumber = CAN_FilterNumber_0; CAN_FilterActivation = ENABLE; CAN_FilterMode = CAN_FilterMode_IdMask; CAN_FilterScale = CAN_FilterScale_32Bit; CAN_FilterID1=0; CAN_FilterID2=0; CAN_FilterID3=0; CAN_FilterID4=0; CAN_FilterIDMask1=0; CAN_FilterIDMask2=0; CAN_FilterIDMask3=0; CAN_FilterIDMask4=0; CAN_FilterInit(CAN_FilterNumber, CAN_FilterActivation, CAN_FilterMode, CAN_FilterScale,CAN_FilterID1, CAN_FilterID2, CAN_FilterID3, CAN_FilterID4,CAN_FilterIDMask1, CAN_FilterIDMask2, CAN_FilterIDMask3, CAN_FilterIDMask4); / Enable Fifo message pending interrupt/ / Message reception is done by CAN_RX ISR*/ CAN_ITConfig(CAN_IT_FMP, ENABLE); }Here, I am suspecting about my configuration, what configuration need to be change.
